IceBridge Antarctic Mission Flies Final 2012 Flight

One end of the rift in Antarctica's Pine Island Glacier, seen from the NASA IceBridge DC-8 on Oct. 23, 2012. Since its discovery the crack has spread and is now less than one kilometer from completing and producing a large iceberg.

With its protective sea ice barrier melted away, Antarctica's Pine Island Glacier grows ever closer to finally dropping its New York City-sized iceberg into the ocean, according to NASA.
